Adjustment of restart operation (Pr.163 to Pr.165, Pr.611)
• The voltage cushion time at a restart can be adjusted by Pr.163 and Pr.164 as shown in the following figure.
• The stall prevention operation level at a restart operation can be set at Pr.165.
• Using Pr.611, the acceleration time to reach Pr.20 Acceleration/deceleration reference frequency after a restart
operation can be set. This can be set individually from the normal acceleration time.
NOTE
• Changing the Pr.21 setting does not affect the Pr.611 setting increment.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
• When the restart operation is selected, undervoltage (E.UVT) and instantaneous power failure (E.IPF) of the fault output
signals become invalid.
• The SU and FU signals are not output during the restart. These signals are output after the restart cushion time passes.
• Restart operation is also performed after the inverter reset is released or after the retry by the retry function occurs.
Operation command source selection for the CS signal during
communication operation (Pr.162 = "1000 to 1003, 1010 to 1013")
• When "1000 to 1003, or 1010 to 1013" is set in Pr.162, the CS signal input via communication is enabled depending on
the setting in Pr.338 Communication operation command source. (When Pr.162 = "0 to 3, or 10 to 13", the CS signal
can be input via an external terminal only.)

CAUTION
• Provide a mechanical interlock for MC1 and MC2. The inverter will be damaged if power supply is input to the inverter output section.
• When the automatic restart after instantaneous power failure function is selected, the motor suddenly starts (after reset time passes)
when an instantaneous power failure occurs. Stay away from the motor and machinery. Apply the supplied CAUTION stickers to easily
visible places when automatic restart after instantaneous power failure has been selected.
